Market Square

Since 1937

Market Square (formerly the Western Furniture Exchange and Merchandise Mart, the San Francisco Mart, and, colloquially, the Twitter Building) is an Art Deco building in the Mid-Market neighborhood of San Francisco, California, United States. Located at 1355 Market Street, it was constructed in 1937 and originally served as a showroom for retailers and wholesalers in the furniture industry. In the early 21st century, the building underwent an extensive conversion into office and retail space, and is most well known as the former headquarters of Twitter, Inc.

Why it's on the map

Between 1974 and 1975, Mart 2, a nearby building along Stevenson and Tenth Streets designed by local architect Jorge de Quesada, was constructed and connected to the main building by several skyways.

RMW Architecture and Interiors served as the architectural firm for the project, while BCV Architects + Interiors designed many of the public and retail spaces in the building.
